From Wikipedia:
Mattermost is an open-source, self-hostable online chat service with file sharing, search, and integrations. It is designed as an internal chat for organisations and companies, and mostly markets itself as an open-source alternative to Slack and Microsoft Teams.
It is integrated into GitLab-Omnibus, used by Wikimedia in Wikimedia Chat on Wikimedia Cloud Services as of late summer 2020 and is used in multiple German universities as an GDPR-conform online chat service.
